Harken 75mm Carbo Triple Ratchamatic Block w/ Cam, Block, Becket
The Carbo Ratchamatic® is a load-sensing ratchet block that rolls freely in both directions under low loads and automatically engages the ratchet as loads increase. Shifting between ratchet and light-air modes is seamless.
Footnote: Maximum working loads and breaking loads for blocks based on cam strengths.
